Abstract

One-dimensional motion of self-interstitial atom clusters in A533B steel was observed using high-voltage electron microscopy. The frequency and distance of one-dimensional motion under electron irradiation were measured. One-dimensional motion occurred frequently at room temperature, but it occurred only slightly at 563 K. The frequency of one-dimensional motion was decreased by annealing at 473 K and higher temperatures. The decreased motion frequency gradually increased under prolonged irradiation. Although annealing reduced the motion frequency of clusters that had been formed before annealing, reduction of the motion frequency was not detected for clusters that formed after annealing.
